The goal of pavement design is to specify the characteristics required for quality performance for a given application. Two key components are mix design and structural design. These processes must also take into account external parameters including subgrade characteristics, traffic loading, and the environment.

When designing pavements (both mix design and structural design), there are three fundamental external design parameters to consider: the characteristics of the subgrade upon which the pavement is placed, the applied loads and the environment.

In designing and building pavements, we sometimes casually assume that making a pavement thicker also makes it stronger, but even to the extent this is true, how thick is thick enough? One of the key questions in the structural design of an asphalt pavement is how thick each layer of the structure should be. During … Read more »
